Stevie is not a he but a she--famed British poet Stevie Smith. As portrayed by Glenda Jackson, Stevie escapes her dull middle-class existence through her poetry. Though she takes many a spiritual flight of fancy, she never truly leaves the small apartment wherein all the action of the film takes place. The rest of the cast--all three of them--consists of Mona Washbourne as Stevie's aunt, Alec McCowan as her boyfriend Freddie, and Trevor Howard as "The Man." Stevie is a literal adaptation of the stage play by Hugh Whitemore; the poetic interpolations are from Stevie Smith's own works.
